  • Stench. Any creature that starts its turn within 5 feet of the cavefish zombie must succeed on a DC 10 Constitution saving throw or be poisoned until the start of its next turn. On a successful saving throw, the creature is immune to the zombie‘s Stench for 24 hours.
  • Undead Fortitude. If damage reduces the cavefish zombie to 0 hp, it must make a Constitution saving throw with a DC of 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, the zombie drops to 1 hp instead.


  • Slam. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 5 (1d6 + 2) bludgeoning damage.


This creature looks like a bloated, wet corpse. Its fingers and toes are webbed, and slick, fleshy fins run down its spine and legs, poking through stretches of dead flesh. An overpowering stench of rot surrounds it.

Aquatic Adaptations. The cavefish zombie is an unusual type of undead that occurs when dark magic permeates a lightless, watery environment, such as in an underground lake or the depths of the ocean. Rather than retain the bodily form it possessed in life, the creature’s skin sloughs off from parts of its body as aquatic features burst through its flesh. Its fingers and toes become webbed, and fins form on its back and down its legs.

Decay. The cavefish zombie’s dead tissue holds water, causing it to look bloated and loose and afflicting it with a persistent rot. This rot results in a horrific odor, which follows them whether they are in water or on land.

Undead Nature. A cavefish zombie doesn’t require air, food, drink, or sleep.
